UNITED STATES PATENT @FHEEQ XVILLIAM EOBLE BARRETT, OF MEADVILLE, PENNSYLVANIA.

CORKSCREW.

SPECIFICATION forming part of Letters Patent No. 388,945, dated September 4, 1888.

Application filed November 12, 1887. Serial No. 254 990. (No model.)

To all whont it may concern:

Be it known that 1, WIL IAM NOBLE BAR- RETT,aeitizeu of the United States,residing at Mead ville, in the county of Crawford and State ofPenusylvania,have invented certain newaud useful Improvements in Corkscrews; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

The special object of the invention is to im prove that class of corkserews which are operated by a lever.

Figure l of the drawings is an elevation in perspective; Fig. 2, a side elevation with the case and nutsin vertical section; Fig. 3, a per spective detail view of the slide-nut; Fig. 4, a similar view of the drive nut with its rack.

In thedrawings, A represents the case-sup port with the flat base a, having screw-holes a a, so that it may be attached to a table, shelf, or bracket. At one side of the front end of this support is the circular rack a, while on the arm 0' of case 0 is formed a corresponding rack, 0". Through the middle of these racks passes a pivot, 13, so that the case C may be set at any desired angle to its support A. The case 0 is slotted at 0 and in this slot travels a screw, (Z, on the slidenut D, so that the latter may move up and down for the length of the slot.

E E are two screws, having, respectively, right and left threads, separated by the piece 6. On the screw Eworksa drivenut, F, with a corresponding thread and with the outside raek,f. In the latter works,through the caseslot 0, the toothed sector 9, which is made in tegral with or fast to the end of the handlever G. This lever is fulcrunicd on a pivot, g, in the case-arms a a. When the lever G is lifted,the nuts and screws more down with the rack until the screw d reaches the bottom wall of the case-slot c. The screw E then bites upon the cork, and as the lever continues to rise works into the cork, while the screw E revolves and the nut F moves down upon it as well as with it, the pitch of the thread upon the screw E being much greater than upon the screw E, so that the motion of the screw E and nut F gives a downward movement or feed to the screw E. This feed continues until the levers sector has ceased to actuate the rack.

In order to draw the cork out of the bottle, a downward pressure is-given to the lever,aud this lifts the rack, screws, and nuts until the screw (1 reaches the upper wall of its slot 0 when the cork will have been drawn out. By acontinued movement of the handlever the screw E works out of the cork and the operation is completed.

Having thus described all that is necessary to a full understanding of my invcntion,what I claim as new, and desire to protect by Letters Patent, is-

The combination,with the case G, slotted at c cand the nut D,carrying' screw (Z in slot 0, of the right and left screws E E on the same stem, the drive-nut F, having outside rack, f, and the toothed sector on lever G, whereby a corkscrew may be Operated in the manner and for the purpose set forth.
